JOSEPH K. SHARPE, JR., OF INDIANAPOLIS, INDIANA, ASSIGNOB. T THE INDIANAMANUFACTURING COMPANY, 0F INDIANAPOLIS, INDIANA, A CORPORATION OF Y WESTVIRGINIA PNEUMATIC STACKER.

To all whom t may concern Be it knownithat I, JOSEPH K. SrrAR'rE, J r.,a citizen of the United States, residing at Indianapolis, in the countyof Marion and State of Indiana, have invented certain new and usefulImprovements in Pneumatic Staclrers, of which the following is aspecification. l

My said invention relates to certain 1mprovements in pneumatic stackersof the character shown and described in my ap- I plication Serial No.489,056, filed April 10,

1909; and it consists in certain details of construction andarrangements of parts whereby I am enabled to provide a convergent.material-deflecting wall in stackers comprising squaremateriaLreceiving chambers without modification ofthe frameworklthereof, all as will be hereinafter more fully pointed o-ut.

The accompanying drawings illustrate my said invention.

Figure 1 is a perspective view of a pneumatic stacker embodying myinvention; Fig. 2, a plan; and Figs. 3 and l are detail elevations ofportions ofthe material deflector forming part of my invention.

In said drawings the portions marked. 5

represent the usual fan-structure; 6, the ejecting chute; 7 the walls orcasing of the material-receiving chamber, and, 8, a fragment of aseparator casing. The hopper, 10, is or may be of a concave or otherform and preferably horizontally positioned transversely at the lowerend of the material-receiving chamber. As fully pointed out in myapplication hereinbefore referred to, it is necessary that materialfalling into the hopper be instantly directed into the inuence of thestacker fan; and for this purpose I provide a removable deflector, 11,extending substantially from one side of the rear of the separator, orfrom the front end of the material-receiving chamber, diagonally acrossthe chamber and hopper to the rear wall of said chamber, by whicharrangement, as clearly shown in Fig. 2, said chambe is caused toconverge toward its rear s1 e. h

A stacker, when attached to a separator, as will be readily understood,becomes substantially a permanent part of the entire machine; and as itbecomes necessary at times to remove sieves or other structures from theseparator, which is frequently ac- Speceation of Letters Patent.

complished through the roof above the stacker fan, I provide my improveddeflector in removable form, so that it or a portion thereof may bewithdrawn, and ample space thus obtained for readily removing the partsmentioned through the side of the chamber at which said deflector islocated. In the arrangement shown, therefor, (see. particularly Figs. 3and Ll), I make the: lower member, 15, of said deflector of a form tolit into the hopper 10, where it may be secured in vertical position inany desired manner, the upper portion thereof being,I preferablyreinforced by a strip, 16, or other wise, as may be found expedient. Theupper member, 18, of said deflector is supported by a suitable frame, 19or otherwise, so that it may be securely fitted onto said lower mem--ber, the wall thereof overlapping said lower member, as indicated inFig. 3. On the upper side of said member 18 I provide an inclined orconed detlector, 20, preferably secured to a frame, as 20, which may beav permanent part of said upper member, or may be separable therefromand supported by the casing 7 or otherwise. These members 15 and 18 maybe detachably secured together at their meeting ends by the clampingnuts, 21, 21, or in any desired manner, By this arrangement I provide adeflector extending diagonally across the material receiving chamber, aswell as an upper delector, as indicated in Fig. 1. The deflector 20,however, may be dispensed with where the conveyers terminating at therear end of the separator are of a character to permit the extension ofthe deflector member 18 approximately to the roof of thematerial-receiving chamber.

As a considerable portion of chaff and light material discharges intothe hopper across the reciprocating apron, 25, and to some extent at theside opposite the stacker fan, I provide a de flector, Q6, which may besecured to the separator or deflecting wall in any desired manner, andheld divergentV therefrom by a brace, 27, or otherwise, by whichdeflector such materialis turned toward and into said fan.

While my improved adjustable delecting wall may be applied to a stackeralready constructed and having a hopper which extends entirely acrossthe material-receiving chamber, I desire to be understood as notlimiting myself to this exact arrangement,

as I may so reduce said hopper in size as to terminate it at itsjunctionwith said diagonal deector; my object being to so construct said chamberas to insure that material will immediately be directed toward the fanwithout the employment of conveyers, inclined hoppers, or otherspecially designed mechanisms.

I claim as my invention:

l. In a pneumatic stacker, t-he combination of a material-receivingchamber comprising a substantially vertical diagonally arrangedremovable deflecting supplemental wall inclined inwardly from the frontto the rear of said chamber, a vertically arranged fan in said chamberat the side thereof opposite to said wall, and a hopper at the lower endof said chamber.

2. A pneumatic stacker comprising a material-receiving chamber embodyinga horizontally arranged hopper, a vertically arranged removablyattachable deiiecting supplemental wall inclined inwardly from the frontto the rear of said chamber and forming the end wall for said hopper, anup* wardly and outwardly inclined deflector at the upper end of saidwall, and a vertically arranged fan in the side of said chamber oppositeto said deflecting wall.

3. In a pneumatic stacker, a material-receiving chamber comprising aremovable diagonallyarranged supplemental wall inclined inwardly fromthe front tothe rear of said chamber, a fan arranged vertically at theopposite side thereof, a horiZontally-arranged hopper at the lower endof said chamber, and a chaff deiiector adjacent said diagonal wall fordirecting materialtoward said fan.

4;. The combination, with a separator, of a pneumatic stacker having amaterial-receiving chamber comprising a vertical defleeting supplementalwall inclined inwardly from the front to the rear of said. chamber aportion whereof is removable to permit withdrawal of structures .fromsaid separator, means for securing said, removable wall portion inposition, a fan vertically arranged at the side of saidchamber oppositeto said deflecting wall, and a hopper in said chamber communicating withsaid fan.

5. In a pneumatic stacker, a material-receiving chamber embodying asectional deiiecting wall inclined from the front to the rear of saidchamber, means' for supporting the sections of said wall, means foruniting said sections in the same vertical plane, a fan verticallyarranged at the side of said chamber opposite to said deflecting wall,and a substantially horizontally arranged hop per in said chambercommunicating with said fan. Y

6. In a pneumatic stacker, a material-receiving chamber having asubstantially vertical deflecting wall inclined inwardly from the frontto the rear of said chamber, an upwardly and outwardly'inclineddeflector at the' upper end of said wall, a fan vertically arranged atthe side of said chamber opposite to said deflecting wall, and a hopperin said chamber communicating with said fan.

7. In a pneumatic stacker, a material-receiving chamber having asubstantially vertical deflecting wall inclined inwardly from the frontto the rear of said chamber and comprising detachable members, an upHKwardly and outwardly inclined deflector at the upper end of said wall, afan vertically arranged at the side of said chamber opposite to saiddeflecting wall, and a substantially horizontally arranged hopper insaidl chamber communicating with said fan.

In testimony whereof I afliX my signature in presence of two witnesses.
